    3、ISO 11997-2 as aBritish Standard. However, attention is drawn to the fact that theUK committee voted against its approval as a standard in CEN andISO. The UK committee have agreed that clause 8.4 should havebeen specified further with respect to the test cycle (durations oflight and dark periods). T

    4、he committee are of the opinion thatthe informative Annex A should have been omitted to avoid anymisunderstanding regarding alternative test procedures. Further, theUK committee feel that the method referenced in A.3.3.1 is not acyclic corrosion test and is therefore outside of the scope of the ISO1

    5、1997 series. For these reasons, a negative vote was submitted.The UK participation in its preparation was entrusted to TechnicalCommittee STI/10, Test methods for paints.A list of organizations represented on this committee can beobtained on request to its secretary.This publication does not purport

The work of preparing Int

    24、ernational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison w

    25、ith ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directive

    26、s, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the e

    27、lements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

    32、working permitted without license from IHS-,-,-BS EN ISO 11997-2:2013ISO 11997-2:2013(E)IntroductionCoatings of paints, varnishes and similar materials are exposed to cyclic wet and dry corrosion and UV exposure conditions using specified salt solutions in cabinets in order to simulate, in the labor

    33、atory, processes occurring in aggressive outdoor conditions. Generally, valid correlations between such outdoor weathering and laboratory testing cannot be expected because of the large number of factors influencing the breakdown process. Certain relationships can only be expected if the effect on t

    34、he coating of the important parameters (e.g. nature of the pollutant, spectral distribution of the incident irradiance in the relevant photochemical region, temperature of the specimen, type and cycle of wetting and relative humidity) is known. In contrast to outdoor weathering, laboratory testing i

    35、n a cabinet is performed with a reduced number of variables, which can be controlled and therefore the effects are more reproducible.The method described can give a means of checking that the quality of a paint or paint system is being maintained. The method is intended to provide a more realistic s

    36、imulation of these factors than is found in traditional tests with continuous exposure to a static set of corrosive conditions. The method has been found to be useful in comparing the cyclic salt spray resistance of different coatings. It is most useful in providing relevant ratings for a series of

    37、coated panels exhibiting significant differences in cyclic salt spray/UV exposure resistance tested at the same time and to the same test cycle.The cycle specified in this part of ISO 11997 has been found useful for air-drying industrial maintenance coatings on steel; other cycles may be used as req
